Satellite Communication
Satellite communication for cruisers has gotten complicated with all the Starlink hype, Iridium options, and competing services flying around. As someone who has relied on sat comms for weather updates, check-ins, and the occasional emergency while offshore, I learned everything there is to know about what actually works out there — and what’s just marketing. Today, I will share it all with you.
When you’re 500 miles from shore, your connection to the outside world comes down to whatever gear you’ve got mounted on the hardtop or the mast. That’s a reality check that hits different from scrolling through product reviews at the kitchen table. I’ve had systems fail at the worst possible moments, and I’ve had cheap backup options save the day. The price tag doesn’t always correlate with reliability.
What Actually Matters for Offshore Comms
Probably should have led with this section, honestly. Before you spend thousands on satellite hardware, figure out what you actually need it for. Weather data? Emergency calling? Sending emails to family? Each use case points to a different solution. Prepare your vessel with redundancy — a primary system and a backup that works on a completely different network. Develop your skills with SSB radio as a fallback, because the old technology still works when everything else goes dark. Plan conservatively on bandwidth expectations, because offshore satellite service is nothing like your home Wi-Fi. That’s what makes satellite communication endearing to us passagemakers — when it works, it connects you to critical information and the people who care about you, no matter where you are on the water.
